Absorbent pad and related methods

ABSTRACT

An absorbent pad. A first side of the absorbent pad is configured to abut a patient at a fluid discharging area or other location. Discharging fluid passes through a fluid-permeable liner of the absorbent pad into absorbent material. Liquid may be placed in the absorbent material prior to placing it on a patient and heated or cooled. An overwrap may be wrapped around the patient to hold the hot or cold compress in place while absorbing discharging fluid from the patient. A fluid barrier at a second side of the absorbent pad, parallel with the first side, prevents liquid from passing out of the absorbent pad at the second side. A coupler having hooks is disposed on the second side of the absorbent pad and is configured to engage with fibers of the overwrap in order to secure the absorbent pad in place with respect to the patient and overwrap.

DESCRIPTION

This disclosure, its aspects and implementations, are not limited to the specific components or assembly procedures disclosed herein. Many additional components and assembly procedures known in the art consistent with the intended absorbent pads and related methods and/or assembly procedures for an absorbent pad will become apparent for use with particular implementations from this disclosure. Accordingly, for example, although particular implementations are disclosed, such implementations and implementing components may comprise any shape, size, style, type, model, version, measurement, concentration, material, quantity, and/or the like as is known in the art for such absorbent pads and related methods and implementing components, consistent with the intended operation.

Referring now to FIGS. 1-4, in implementations absorbent pads 2 and 20 include a first side 6 and a second side 8 substantially parallel with the first side 6. The first side 6 and second side 8 at least partially form a cavity 10. In the implementations shown the cavity 10 is fully enclosed within the fluid-permeable liner 4 though in other implementations it may not be fully enclosed within the fluid-permeable liner 4. An absorbent material 12 is disposed at least partially within the cavity 10. In the implementations shown the absorbent material 12 is disposed fully within the cavity 10.

The fluid-permeable liner 4 is configured to abut a fluid discharge area of a patient, whether human or animal. In the implementations of FIGS. 1-2 and FIG. 4 the fluid-permeable liner 4 forms the first side 6 and second side 8 of an absorbent pad 2. In the implementation of FIG. 3 the fluid-permeable liner 4 forms only the first side 6 of an absorbent pad 20, with the second side 8 being formed by a fluid barrier 22, and the fluid barrier 22 and fluid-permeable liner 4 are joined together at their outer edges. This joining may be accomplished, by non-limiting example, by an adhesive, melting, stitching, gluing, and the like.

In implementations absorbent pads 2 and 20 have a coupler 14 coupled to the second side 8. In the implementation illustrated in FIGS. 1-4, the coupler 14 has hooks 16 which extend outwardly from the second side 8 in a direction away from the first side 6. In other implementations, however, the coupler 14 may be formed from any other structure adapted to releasably or removably engage with or couple with the material of an overwrap 18.

Referring now to FIG. 4, while in use the absorbent pad 2 may be placed proximate a fluid discharge area or another desired location of a patient with the first side 6 facing the fluid discharge area or other desired location on the patient's body. The second side 8 and the hooks 16 of the coupler 14 then face away from the fluid discharge area. An overwrap 18 may then be wrapped around the patient proximate the fluid discharge area or other desired location. The hooks 16 engage with fibers included in the material of the overwrap 18 to secure the absorbent pad 2 in place with respect to the patient and the overwrap 18. In implementations the hooks 16 when engaged with the fibers of the overwrap 18 together form a hook-and-loop fastener. This behavior may be observed particularly in implementations where the overwrap 18 is composed of a fabric or other woven material, such as an ACE™ bandage. In various implementations the fibers need not form or be composed of closed loops but may still function to allow the hooks 16 to engage with the fibers to secure the absorbent pad 2 in place. When an absorbent pad 2 is used the portion of the fluid-permeable liner 4 that forms the first side 6 faces towards the patient and the portion of the fluid-permeable liner 4 that forms the second side 8 faces away from the patient. In implementations wherein an absorbent pad 20 like that illustrated in FIG. 3 is used, the fluid-permeable liner 4 faces the patient and the fluid barrier 22 faces away from the patient. The absorbent pad 20 may be secured in place in the same way as described above with respect to the absorbent pad 2.

In various implementations absorbent pads 2 and 20 are configured to be used at or near a wound of a patient to absorb fluids discharging from the patient and/or to also be used as a hot or a cold compress. The fluids may therefore be biological fluids or “biofluids” as they are commonly known in the art, including any liquid originating from the body of a living person or animal such as, by non-limiting example, blood, urine, feces, water, saline (such as a saline irrigating solution that is used to flush and/or cleanse a patient's eye or other body portion), vaginal secretion, birthing fluids and so forth. The fluids may be biohazardous. The patient may be a human or an animal. A fluid discharge area may include, by non-limiting example: a bleeding or otherwise fluid-discharging wound, abscess, injury, scrape, cut, puncture, burn, bruise, laceration, gash, amputation or incision; vaginal discharges before, during, and/or after a vaginal or c-section birthing and/or during a menstruation; urinal discharges; fecal discharges; and the like. A fluid discharge area may also include an overspill area where all or some of the fluid is not originating from a patient such as, by non-limiting example, an area near an eye of the patient that is being flushed with irrigating saline solution, wherein the absorbent pad 2 or 20 is placed nearby to absorb the irrigating saline solution, or any other area of a patient's body where irrigating solution is used for flushing, irrigating or otherwise cleaning the area of the patient's body. A fluid discharge area may also include a location underneath a patient where an absorbent pad 2 or 20 is placed to absorb overspill of some irrigating or other fluid to prevent it from soiling a mattress or other item underneath the patient, or to similarly capture urination or feces from an incontinent patient.

A desired location of a patient, for instance for use of the absorbent pad 2 or 20 as a hot or cold compress, could include any of the fluid discharge areas described above, or any others, and could also include, by non-limiting example: a bruise; black eye; contusion; swelling; bone fracture; sprain, and the like. In FIG. 4 the fluid discharge area/desired location is shown on the torso of a human patient. In other implementations the fluid discharge area/desired location may be at or proximate any portion of the body of a human or non-human animal patient including the head and all limbs, extremities, torso, stomach, back, neck and the like. Accordingly, the absorbent pads 2 and 20 in particular implementations are flexible so as to conform to the contour of the portion of the patient's body where they are placed. In areas of the body with hair the absorbent pad 2 or absorbent pad 20 may be used with or without removing or reducing the hair at the fluid discharge area or other desired location of a patient.

In implementations an adhesive may be placed on the first side 6 to adhere the fluid-permeable liner 4 to the fluid discharge area or other desired location of the patient. This adhesive could be in the shape of a strip similar to the shape of the coupler 14 shown in the drawings and may include a removable portion to be used during pre-use storage and removed when it is desirable to adhere the fluid-permeable liner 4 to the discharge area.

In implementations the fluid-permeable liner 4 includes spunbond polypropylene supplied by ATEX, Inc. of Gainesville, Ga. and sold under the product name of AXAR Hydrophilic, and having a composition of polypropylene between about 94-98 weight percent, color pigment between about 2-6 weight percent, and mixture of nonionic emulsifiers and special antistatic agents of about 0.2-0.8 weight percent. In other implementations the fluid-permeable liner 4 may include any other fluid-permeable natural or synthetic material. In implementations the fluid-permeable liner 4 may also include an antimicrobial agent.

In implementations the absorbent material 12 includes one or more absorbents and/or one or more superabsorbents and/or one or more antimicrobial agents. In implementations the superabsorbent includes about 5% to 65% of the weight of the combination of absorbent(s), superabsorbent(s) and antimicrobial agent(s). In implementations the superabsorbent is a nonwoven superabsorbent. In implementations the antimicrobial agent(s) include about 0.005% to 1% of the total weight of the combination of absorbent(s), superabsorbent(s) and antimicrobial agent(s). In implementations the absorbent material 12 is configured such that the absorbent pad 2 or 20 is able to absorb up to thirty times its weight in fluid. In implementations the absorbent material 12 may be configured to absorb up to about 15 times its weight of 0.9% normal saline solution and up to about 30 times its weight of water.

In implementations the absorbent pads 2 and 20 may absorb up to ten times more than a conventional absorbent pad commonly known in the industry as a “chux” or “blue pad.” In implementations an absorbent of the absorbent material 12 includes a matrix of Kraft fluff pulp and bonding fiber and the superabsorbent includes microscopic super absorbent polymer (SAP) beads and/or olefin/alkyl carboxylate co-polymer and/or an inorganic salt, each of which may be technical grade. In implementations the microscopic SAP beads are hydrophilic. In various implementations, additional chemicals may be included such as, by non-limiting example, zeolite, silver, zinc, iodine, copper, and ammonium.

In implementations the coupler 14 could include some other coupling mechanism other than hooks 16 such as, by non-limiting example: fibers, loops, an adhesive, and the like. In implementations the overwrap 18 may be an elastic bandage, ACE bandage, elastic wrap, compression bandage or crepe bandage or any other type of overwrap or dressing. The overwrap 18 may be tightened in order to increase pressure to a fluid discharge area or may be loosened to decrease pressure.

In implementations the absorbent pad 2 or 20 is configured such that fluid emanating from a fluid discharge area or fluid which is intentionally placed into the absorbent pad 2 or 20 at the surface of the fluid-permeable liner 4 moves away from the fluid-permeable liner 4 into the absorbent material 12 such that the fluid-permeable liner 4 remains dry to the touch during or shortly after use.

In implementations the absorbent material 12 includes an antimicrobial agent. In implementations the antimicrobial agent may include a silver ion antimicrobial agent supplied by AgION Technologies of Wakefield, Mass. including sodium aluminosilicate (zeolite), silver, zinc and ammonium and having the chemical formula X_(2/n)O—Na₂O—Al₂O₃-2SiO₂, where “X” is the cation of each of the previously listed chemicals. The zeolite may be zeolite A (CAS number 68989-22-0). Some or all of the antimicrobial agent may be included in the absorbed material in the form of about 1-2 micron particles. In implementations the antimicrobial agent is configured to inhibit microbial growth proximate the fluid discharge area or other desired location of a patient. Other antimicrobial agents that may be included may be those that contain iodine or copper ions.

The fluid barrier 22 is configured to disallow or discourage fluid from passing through it. The fluid barrier 22 may also have high coefficient of friction with a common floor surface, tabletop surface, stretcher or other material or surface such as to give it anti-slip properties. In implementations the fluid barrier 22 includes a polymeric film supplied by Pliant Corporation of Schaumburg, Ill. and includes one or more of the following: linear low density polyethylene (LDPE), medium density polyethylene (MDPE), high density polyethylene (HDPE), ethane, copolymer Polyolefin/Ethene, Octene-lHomopolymer, LLDPE, mLLDPE, or uLLDPE/LDPE.

In implementations the absorbent pad 2 or 20 is configured to assist in/and or facilitate the solidification of bio fluids emanating from a fluid discharge area of a patient such as, by non-limiting example, a jellification process by which water molecules of the bio fluid adhere to the surface of microscopic SAP beads in the absorbent material 12 and form a gel and the non-water remnant of the bio fluid then comprises solid particles.

Various implementations of absorbent pads 2 and 20 may be used in a method of using an absorbent pad 2 or 20 as a hot or cold compress. In such instances the absorbent material 12 is configured to retain a predetermined amount of liquid such as, by non-limiting example, water, and enable the retained liquid to be cooled or heated. The absorbent pad 2 or 20 may then be placed on or against a desired location of a patient's body and, although it already has absorbed some liquid, is capable of additionally absorb more liquid emanating from a fluid discharge area of a patient. Thus the absorbent pad 2 or 20 may function both as a hot or cold compress and simultaneously to absorb issuing fluids.

One implementation of a method of using an absorbent pad 2 or 20 as a compress may include absorbing a predetermined quantity of liquid into an absorbent pad 2 or 20 having a fluid-permeable liner 4 in a first side 6 of the absorbent pad 2 or 20, the absorbent pad 2 or 20 having an absorbent material 12 configured to absorb a maximum quantity of liquid greater than the predetermined quantity of liquid and further having a second side 8 substantially parallel with the first side 6. The predetermined quantity of liquid may be heated and/or cooled to a desired temperature and the absorbent pad 2 or 20 may be placed at a desired location of a patient. Liquid may be prevented from passing through the second side 8 of an absorbent pad 20 with a fluid barrier 22. The absorbent pad 2 or 20 may be secured to the desired location through the engagement of hooks 16 on the second side 8 with fibers in an overwrap 18 wrapped around the patient at the desired location.

A predetermined quantity of liquid may be heated to a desired temperature by microwaving the absorbent pad 2 or 20. The predetermined quantity of liquid may be cooled to a desired temperature by cooling the absorbent pad 2 or 20 in a refrigerator or freezer. The absorbent pad 2 or 20 may be adhered to the desired location of the patient with an adhesive. Microbial growth proximate the desired location may be inhibited through the use of an antimicrobial agent dispersed in the absorbent material 12. The predetermined quantity of liquid may be retained within the absorbent material 12 while additional liquid from a fluid discharge area of a patient is additionally absorbed into the absorbent material 12. The absorbent pad 2 or 20 may maintain a substantially dry surface at the fluid-permeable liner 4 after absorbing liquid from a fluid discharge area of a patient by drawing the liquid from the fluid discharge area of the patient into the absorbed material away from the fluid-permeable liner 4. The absorbent material 12 may absorb up to about 15 times its weight of 0.9% normal saline solution and up to about 30 times its weight of water. In various implementations of the method, the method may further include absorbing a quantity of fluid issuing from the patient.

Another implementation of the method may include absorbing a predetermined quantity of liquid into the absorbent material 12 of an absorbent pad 2 through a fluid-permeable liner 4 included in a first side 6 and in a second side 8 of the absorbent pad 2, the predetermined quantity of liquid being less than a maximum quantity of liquid absorbable by the absorbent material 12 and the fluid-permeable liner 4 at least partially surrounding the absorbent material 12; one of heating or cooling the liquid to a desired temperature; placing the first side 6 onto a desired location of a patient; and securing the absorbent pad 2 to the fluid discharge area by coupling an overwrap 18 to a second side 8 of the fluid-permeable liner 4, where the second side 8 is substantially parallel with the first side 6; and where coupling the overwrap 18 to the second side 8 includes causing loops of the overwrap 18 to engage with hooks 16 of the second side 8, thereby forming a hook-and-loop fastener. Method implementations may likewise include absorbing a quantity of fluid issuing from a patient.

Another method of using an absorbent pad 2 or 20 may include providing an absorbent pad 2 or 20 having a fluid-permeable liner 4 in a first side 6 of the absorbent pad 2 or 20 and a fluid barrier 22 in a second side 8 of the absorbent pad 2 or 20, the absorbent pad 2 or 20 having an absorbent material 12 configured to absorb a predetermined quantity of liquid, the predetermined quantity of liquid being less than a maximum quantity of liquid absorbable by the absorbent material 12; wherein the absorbent pad 2 or 20 is further configured to: allow heating and cooling of the predetermined quantity of liquid in the absorbent material 12 to a desired temperature; and allow the first side 6 of the absorbent pad 2 or 20 to contact a desired location of a patient. In implementations the predetermined quantity of liquid is one of 0.5 cups, 0.75 cups, 1 cup and 1.5 cups,

In various method implementations the absorbent pad 2 or 20 may be heated and/or cooled in the following manner: preloading the absorbent pad 2 or 20 with fluid which may consist of warm tap water poured evenly over the absorbent pad 2 or 20; letting the absorbent pad 2 or 20 stand until water cannot be squeezed out (which may take about a minute in particular implementations), then heating the absorbent pad 2 or 20 in a microwave oven for about 1-2 minutes (for a hot absorbent pad 2 or 20) or placing the absorbent pad 2 or 20 in a freezer for about an hour and then microwaving it for about 30 seconds (for a cool absorbent pad 2 or 20). In implementations wherein the absorbent pad 2 or 20 has a size of about 3.5 inches by 12 inches the absorbent pad 2 or 20 may be preloaded with about 0.5 cup of water. Other pad sizes may have the following preload amounts: 4 inch by 14 inch—about 0.75 cups water; 5 inch by 16 inch—about 1 cup water; 6 inch by 18 inch—about 1.5 cups water; 9 inch by 9 inch—about 1 cup water.

In various implementations the absorbent pads 2 and 20 are configured to be microwaveable without being damaged, thus allowing heating of the predetermined amount of liquid by microwaving. However, other methods, such as heating the pad using a heated surface such as a hot plate may also be used.

In various implementations an absorbent pad 2 or 20 could be used together with a stick, such as a broom stick, or other pushing/pulling implementation or apparatus, to form a cleaning apparatus that could be used to clean a floor surface. The stick or other pushing/pulling apparatus may have loops or fibers or some other item to engage with the hooks 16 of the absorbent pad 2 or 20 to couple the two together when desired and to remove the two when desired, such as for cleaning or replacing of the absorbent pad 2 or 20. An example of such an absorbent pad implementation can be found in FIG. 2 and the corresponding disclosure of U.S. Provisional Patent Application 61/392,942, entitled “Dressing Systems, Fluid Management Systems, Hot/Cold Pack Systems and Related Methods” previously incorporated by reference.

In implementations the absorbent pads 2 and 20 may be used to absorb irrigation solution such as, by non-limiting example, saline solution used to flush a patient's eye or other body portion. In such an implementation the absorbent pad 2 or 20 may be placed below the patient such as on a bed or other item upon which the patient sits or lies. An absorbent pad 2 or 20 may be heated or cooled and placed underneath an animal such as a dog, as a warming pad after a surgery or at any other time when a warming pad is desired, or as a cooling pad for instance during transportation of an animal.

In places where the description above refers to particular implementations of absorbent pads and related methods, it should be readily apparent that a number of modifications may be made without departing from the spirit thereof and that these implementations may be applied to other absorbent pads and related methods.
